VT machining offers CNC Bending for SECC Steel (JIS G3313 electro-galvanised SPCC), typically supplied cold-rolled, EG coated. Thin, smooth zinc coating for painted or bare electronics enclosures.
CNC Bending Notes for SECC Steel
SECC Steel bends to a tight inside radius (about 1× thickness) in this condition.
For estimating, a 100 × 100 × 10 mm block of SECC Steel weighs about 0.79 kg.
